\({\log _a}a = 1\) (since \({a^1} = a\)) so \({\log _7}7 = 1\) \({\log _a}1 = 0\) (since \({a^0} = 1\)) so \({\log _{20}}1 = 0\) \({\log _a}p + {\log _a}q = {\log _a ...

In mathematics, the division of numbers may involve negative exponents in the denominator. Such questions can be easily solved with the help of the properties of logarithms and log tables. For better ...

The North Pole is warmer than ever, and some weather experts say this is why Sandy took an uncharacteristic detour to the Jersey Shore. This summer, scientists reported that Arctic sea ice was at the ...
